I use the Firefox 4.0 Beta 2 with WebGL. I want to make the user can printout his/her 3D Artwork in WebGL. But the browser or the printer read the canvas Picture upside down. (y-flip). I know WebGL see the y coord 0 at the bottom of the canvas.

I did not found a CSS command to flip the canvas to printmedia.
Is this a bug or a feature? :) What could I do?
